TVR Instruments are pleased to announce the addition to the Ziehl Industrie elektronik range of temperature protection relays of the TR640IP and the TR660IP.

The two new additions to the Ziehl Industrie elektronik range of temperature measuring and monitoring relays are the TR640IP and the TR660IP. Both units offer inputs for up to sensors either 6 x Pt 100, Pt 1000, or PTC thermistors. Different sensors can be connected at the same time, e.g. Pt 100 (RTD) and PTC-thermistors.

The TR640IP has 4 limit relays and remote monitoring via TCP/IP connectivity, whilst the TR660IP has 7 limit relays, remote monitoring via TCP/IP LAN and the option of 4 analogue outputs programmable 2 x 0/4 - 20 mA and 2 x 0/2 - 10 V or RS485 RTU. 

Typical applications are monitoring of motors, generators, or transformers. Another application is the use as a 2- or more step- controller with additional monitoring of over- or under temperature or monitoring of differences in temperatures of 2 sensors. Pre-set programs allow easy setting e.g. monitoring of transformers with/without monitoring of temperature of core or with/without controlling a ventilator.

Designed for DIN rail mounting they add to the range of panel and rail mounting temperature protection devices which Ziehl manufacture.
